    text
    copied!<p>I got a tableView with custom cells. Inside each of these cells, there's a UILabel, which get it's text from an NSMutableArray. I set up a GestureRecognizer to see if this label is tapped or not. And if it's tapped, I go to another view. </p> <p>Now in the method associated to the selector for the labels, I would like to get the index of the text in the NSMutableArray, corresponding to the tapped label. How could I do that?</p> <p>Here is some sale code : In the cellForRowAtIndexPath: method, here's what I do :</p> <pre><code> cell.Label.text = [tableLabelText objectAtIndex:indexPath.row]; UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(goToViewControllerB:)]; [cell.Label setUserInteractionEnabled:YES]; [cell.Label addGestureRecognizer:tap]; [tap release]; </code></pre> <p>then I display everything...</p> <p>and here's the goToViewControllerB method :</p> <pre><code>- (void) goToViewControllerB:(id)sender { if (!viewControllerB) { viewControllerB = [[ViewControllerB alloc] initWithNibName:@"ViewControllerB" bundle:nil]; } navigationController = [[UINavigationController alloc] initWithRootViewController:viewControllerB]; [self presentModalViewController:navigationController animated:YES]; } </code></pre> <p>If I do that, and if in my viewControllerB I modify something and go back to the Table View, then click on another label, I will be lead to the same viewControllerB, containing the previous modification. I do want to show a new viewControllerB for each label.</p> <p>My idea was to get the index of tableLabelText corresponding to the tapped Label. The I could, whenever I call the goToViewControllerB:, create a new object of type ViewControllerB and insert it into a NSMUtableArray, at the same index...Something like </p> <pre><code>if ([ViewControllerArray objectAtIndex: "here the index i'm looking for"]){ "show it" } else { "create it and insert it into ViewControllerArray at the right index" } </code></pre>
